A customer has EMC NetWorker integrated with Data Domain. They noticed that they have incorrectly configured their NetWorker Browse and Retention policies for all currently defined clients. This issue was discovered when a DPA report was e-mailed showing the amount of available space on their EMC Data Domain system.
The customer has made the necessary corrections to the Browse and Retention policies.
They have manually deleted save sets that should have been expired based upon the new Browse and Retention times. After comparing the size of the index directory, prior to and after the modification, the customer noticed that the index directory decreased in size by several hundred GB. However, the available space on the Data Domain remained unchanged.
Although NetWorker has deleted the necessary indexes, why does the Data Domain available capacity remain the same?

An EMC NetWorker customer wants to replicate backup data stored on their Data Domain system to a new, offsite Data Domain system. They want the benefits of replicating data in deduplicated format. However, they also want to be able to manage and report on the replicated save sets using NetWorker media database information.
To meet their requirements, which method of storing backup data on the Data Domain system and which type of replication should be used?

An EMC customer has a large Microsoft SharePoint 2010 environment. The environment consists of three separate distributed farms with several web front-end and content database servers. An Avamar solution was deployed to protect this environment, backing up the SharePoint data to Data Domain Boost devices on the back-end. Backup data is replicated by Avamar to a disaster recovery site in another location.
The web front-end server in one of the farms where the front-end plug-in is installed experienced a disaster and all data on that server was lost. What needs to be done to ensure backups continue to run with minimal impact to operations?

An Oracle customer has configured backups of five Oracle servers to their EMC NetWorker server. Over the past month they have been successfully performing hot backups using the NMDA module. Now, one of the databases has become corrupted and they would like to perform a point-in-time recovery of the database.

Scenario 1
You have a customer with a large IBM Lotus Domino environment. The customer is in the process of migrating from a UNIX to a Microsoft Windows infrastructure. As part of this process, they are going to perform a refresh of the hardware and software that Domino is running on. In addition, they will migrate all client backups to a new EMC NetWorker environment. The new backup environment consists of a NetWorker server and two storage nodes running on Windows 2008.
The Domino environment consists of a single server running two instances of Domino. The total amount of data that needs to be backed up is approximately 900 GB. The Domino server will have connections to both the SAN and the LAN. They would like to perform hot backups of the databases using the NMDA but are leaving specific design decisions to you.
Additionally, the customer would like to send all data to disk for onsite backups and clone the first full backup of the year to tape for long-term offsite retention. The backup target infrastructure consists of a single Quantum i2000 tape library with six LTO-4 tape drives inaddition to two EMC Data Domain 890s. One Data Domain will be located at their primary site. The second Data Domain is at the disaster recovery (DR) site as a replication target for the first.
One of the customer's major concerns is the backup speed of the Domino environment.
They are interested in any best practices they can implement to improve backup performance at the Domino level. Furthermore, they are looking for guidance in using NMDA to backup the data and leverage their backup infrastructure in the most efficient way.
Refer to Scenario 1.
To achieve optimal backup performance, which recommendation would you make regarding the disk layout of their Domino server?
